Affinity Peptides With pH Sensitivity for the Enrichment of CD38+ Cells

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT The selective enrichment of cell populations based on surface markers is critical for the advancement of gene and cell therapies. Current antibody‐based cell isolation methods, such as fluorescence‐ and magnetic‐activated cell sorting (FACS and MACS), offer high specificity but are limited by scalability, cost, and potential adverse effects on
